List of unsolved problems may refer to several notable conjectures or open problems in various academic fields: Natural sciences, engineering and medicine [ edit ]
The seven selected problems span a number of mathematical fields, namely algebraic geometry, arithmetic geometry, geometric topology, mathematical physics, number theory, partial differential equations, and theoretical computer science. Unlike Hilbert's problems, the problems selected by the Clay Institute were already renowned among ...
Protein folding problem: Is it possible to predict the secondary, tertiary and quaternary structure of a polypeptide sequence based solely on the sequence and environmental information? Inverse protein-folding problem: Is it possible to design a polypeptide sequence which will adopt a given structure under certain environmental conditions?
Goldbach's conjecture is one of the oldest and best-known unsolved problems in number theory and all of mathematics. It states that every even natural number greater than 2 is the sum of two prime numbers. The conjecture has been shown to hold for all integers less than 4 × 10 18 but remains unproven despite considerable effort.
Goldberg was born on August 2, 1921, in Sacramento, California.He received his B.S. in chemistry from the University of California, Berkeley in 1942, and then, after serving in the Navy during World War II, did his graduate studies under the supervision of Harrison Brown at the University of Chicago, where he received his Ph.D. in chemistry in 1949.
Between 1953 and 1989, Alimarin headed the Department of Analytical Chemistry at Moscow State University (MSU). [1] Between 1963 and 1988, Alimarin was the editor-in-chief of the Journal of Analytical Chemistry. [2] In 1966, Alimarin was awarded the title of academician of the Academy of Sciences of the Soviet Union. [7]
The New Dictionary of Scientific Biography, edited by Noretta Koertge, was published by Scribner's in December 2007 with 775 entries. [6] Nearly 500 of these are new articles about scientists who died after 1980 and thus were not included in the original Dictionary; 75 articles are on figures from earlier periods not included in the original Dictionary of Scientific Biography, including a ...
